94 sportster transmission noises - 1993 Harley Davidson XLH Sportster 883 Hugger

It's more likely that your battery terminals are dirty or have become loose. Clean and check your battery terminals. If I recall correctly (I had a 1993 Sportster as well years ago), I had that happen a few times. Best of luck to you!

With the engine running, put the transmission into gear and sit there with the clutch lever pulled in. Do you still hear the noise. If so, most likely the noise is in the primary itself rather than the transmission. Since you didn't specify whether the bike is a Sportster or a BIg Twin, it's difficult to say what the noise may be. It could be a bearing going bad. The problem with that is that you can disassemble the bike and never find the bearing. It could be the big bearing in the outer clutch shell or it could the mainshaft support bearing in the inner primary if it's a big twin. A Sportster has basically the same bearings but in different areas. If the bike is equipped with one of those automatic primary chain tensioners, I've seen them make a noise as well. Then again, a noise like that is very difficult to find. It seems to travel all through the engine. It could possibly be an inner cam bearing going bad. They sound exactly like the alternator whine on a Chevrolet. If you have one of those mechanic's stethoscopes or long screwdriver, listen to various places on your engine to try to locate the noise more closely.

No, sorry to tell you that you don't need to break a gear in. There is something not quite right in the transmission if it's jumping out of gear. If I had to guess, he probably broke second gear speed shifting the bike, then replaced the gear and go the shimming messed up and it doesn't have the correct engagement with the shifter clutch dogs. To repair this, you'll have to pull the transmission out of the case. If your mechanically inclined, this isn't that difficult but you WILL need a factory service manual to check the transmission to find out what is wrong. Heck, he may have put the gear in backwards. Some of them will work that way but they'll jump out when power is applied or let off.

Good Luck

1994 honda accord automatic transmission makes a reallyy loud noise when i put in revers only

Yes you can, but does the manuf recommend it? I tend to lean towards the oil specially made for bikes. I like the amsoil and all, and I am sure it would be ok, but, there are some people out there that don't like it. So, I guess it is your call. Hope this helps.

• Check the gears of the transmission and checked the release bearing. If the release bearing needs to be change replace it.
• And make sure to buy a new transmission fluid.
• If you need clarification just reply to this solution.

The Sportster has a "cassette" type transmission. The transmission can be removed without the necessity of splitting the cases to get at it like most other motorcycles.

To remove the transmission one must remove the primary drive component that include the compensator sprocket, the primary chain, and the clutch assembly on the left side of the engine. On the right side of the engine, you'll have to remove the rear brake master cylinder, the front chain sprocket cover, and the front chain sprocket.

Going back to the left side of the engine and remove the four bolts that hold the transmission front plate (access cover) to the engine cases. There are two "pry points" on the access cover. Look around the edge of the cover and you will see them. Pry the access cover off gently and the transmission will come out of the engine cases. The shifter shaft will remain in the cases. When you reinstall the transmission, mark the shaft in such a manner that you can tell what position the shifter shaft finger is pointing. It should be level pointing to the rear of the engine as the transmission is reinstalled in the case.

If you can find a Clymer's manual #M428, it explains in detail the removal and repair of the transmission.
